Как изменить цвет текста php

<?php
ini_set("highlight.comment", "#008000");
ini_set("highlight.default", "#000000");
ini_set("highlight.html", "#808080");
ini_set("highlight.keyword", "#0000BB; font-weight: bold");
ini_set("highlight.string", "#DD0000");
?>

Like you see in the example above, you can even add additional styles like bold text, since the values are set directly to the DOM attribute "style".

Also, this function highlights only text, if it begins with the prefix "<?php". But this function can highlight other similar formats too (not perfectly, but better than nothing), like HTML, XML, C++, JavaScript, etc. I use following function to highlight different file types and it works quite good:

<?php
function highlightText($text)
{
    $text = trim($text);
    $text = highlight_string("<?php " . $text, true);  // highlight_string() requires opening PHP tag or otherwise it will not colorize the text
    $text = trim($text);
    $text = preg_replace("|^\<code\>\<span style\="color\: #[a-fA-F0-9]{0,6}"\>|", "", $text, 1);  // remove prefix
    $text = preg_replace("|\</code\>$|", "", $text, 1);  // remove suffix 1
    $text = trim($text);  // remove line breaks
    $text = preg_replace("|\</span\>$|", "", $text, 1);  // remove suffix 2
    $text = trim($text);  // remove line breaks
    $text = preg_replace("|^(\<span style\="color\: #[a-fA-F0-9]{0,6}"\>)(&lt;\?php&nbsp;)(.*?)(\</span\>)|", "$1$3$4", $text);  // remove custom added "<?php "return $text;
}
?>

Note, that it will remove the <code> tag too, so you get the formatted text directly, which gives you more freedom to work with the result.

I personally suggest to combine both things to have a nice highlighting function for different file types with different highlight coloring sets:

<?php
function highlightText($text, $fileExt="")
{
    if ($fileExt == "php")
    {
        ini_set("highlight.comment", "#008000");
        ini_set("highlight.default", "#000000");
        ini_set("highlight.html", "#808080");
        ini_set("highlight.keyword", "#0000BB; font-weight: bold");
        ini_set("highlight.string", "#DD0000");
    }
    else if ($fileExt == "html")
    {
        ini_set("highlight.comment", "green");
        ini_set("highlight.default", "#CC0000");
        ini_set("highlight.html", "#000000");
        ini_set("highlight.keyword", "black; font-weight: bold");
        ini_set("highlight.string", "#0000FF");
    }
    // ...$text = trim($text);
    $text = highlight_string("<?php " . $text, true);  // highlight_string() requires opening PHP tag or otherwise it will not colorize the text
    $text = trim($text);
    $text = preg_replace("|^\<code\>\<span style\="color\: #[a-fA-F0-9]{0,6}"\>|", "", $text, 1);  // remove prefix
    $text = preg_replace("|\</code\>$|", "", $text, 1);  // remove suffix 1
    $text = trim($text);  // remove line breaks
    $text = preg_replace("|\</span\>$|", "", $text, 1);  // remove suffix 2
    $text = trim($text);  // remove line breaks
    $text = preg_replace("|^(\<span style\="color\: #[a-fA-F0-9]{0,6}"\>)(&lt;\?php&nbsp;)(.*?)(\</span\>)|", "$1$3$4", $text);  // remove custom added "<?php "return $text;
}
?>

<?code()?>
  $string = 'Here I put my code';
<?code()?>

And somewhere else define the function:

<?
  function code()
  {
    static $on=false;
    if (!$on) ob_start();
    else
    {
      $buffer= "<?n".ob_get_contents()."?>";
      ob_end_clean();
      highlight_string($buffer);
    }
    $on=!$on;
  }
?>

<?php// Combined of the highlight_string and var_export
function hl_export()
{
    try {
        ini_set("highlight.comment", "#008000");
        ini_set("highlight.default", "#FFFFFF");
        ini_set("highlight.html", "#808080");
        ini_set("highlight.keyword", "#0099FF; font-weight: bold");
        ini_set("highlight.string", "#99FF99");$vars = func_get_args();

        foreach (

$vars as $var ) {
            $output = var_export($var, true);
            $output = trim($output);
            $output = highlight_string("<?php " . $output, true);  // highlight_string() requires opening PHP tag or otherwise it will not colorize the text
            $output = preg_replace("|\<code\>|", "<code style='background-color: #000000; padding: 10px; margin: 10px; display: block; font: 12px Consolas;'>", $output, 1);  // edit prefix
            $output = preg_replace("|(\<span style\="color\: #[a-fA-F0-9]{0,6}"\>)(&lt;\?php&nbsp;)(.*?)(\</span\>)|", "$1$3$4", $output);  // remove custom added "<?php "
            echo $output;
        }
    } catch (Exception $e) {
        echo $e->getMessage();
    }
}// Debug multiple vars at once.
$var1 = 'Example String';
$var2 = 1987;

my solution :
echo str_replace("&nbsp;", " ",highlight_string("Arise, you children of the fatherland",true));
echo str_replace("&nbsp;", " ",highlight_file("test.php",true));

This function outputs valid XHTML 1.1 code by replacing font tags with span tags. You can also specify whether you want it to return or echo, output a line-count, the color of the line-count, and the starting line-count number.

Usage:
<?
// $str = string with php
// $return = true (return) / false (echo)
//    default of false
// $counting = true (count) / false (don't count)
//    default of true
// $start = starting count number
//    default of '1'
// $color = count color with preceding #
//    defalut of '#666'
get_sourcecode_string($str, $return,   $counting, $start, $color);
?>

<?phpfunction xhtml_highlight($str) {
    $str = highlight_string($str, true);
    //replace <code><font color=""></font></code>
    $str = preg_replace('#<font color="([^']*)">([^']*)</font>#', '<span style="color: \1">\2</span>', $str);
    //replace other <font> elements
    return preg_replace('#<font color="([^']*)">([^']*)</font>#U', '<span style="color: \1">\2</span>', $str);

Find the function here :
http://www.tellinya.com/art2/262/highligh-php-syntax/
and ditch the old PHP one permanently.
Tested and built on PHP 5.2.0.

Looking forward to any input.

<?
function xml_highlight($s){
  $s = preg_replace("|<([^/?])(.*)s(.*)>|isU", "[1]<[2]\1\2[/2] [5]\3[/5]>[/1]", $s);
  $s = preg_replace("|</(.*)>|isU", "[1]</[2]\1[/2]>[/1]", $s);
  $s = preg_replace("|<?(.*)?>|isU","[3]<?\1?>[/3]", $s);
  $s = preg_replace("|="(.*)"|isU", "[6]=[/6][4]"\1"[/4]",$s);
  $s = htmlspecialchars($s);
  $s = str_replace("t","&nbsp;&nbsp;",$s);
  $s = str_replace(" ","&nbsp;",$s);
  $replace = array(1=>'0000FF', 2=>'0000FF', 3=>'800000', 4=>'FF00FF', 5=>'FF0000', 6=>'0000FF');
  foreach($replace as $k=>$v) {
    $s = preg_replace("|[".$k."](.*)[/".$k."]|isU", "<font color="#".$v."">\1</font>", $s);
  }

  return nl2br($s);
}
?>

I'm sorry, I completely forgot about str_ireplace being for PHP 5 for some reason. Also, there was another error I missed (too many late nights ;)). Here's the corrected code:

<?php
    function highlight_code($code, $inline=false, $return=false) // Pre php 4 support for capturing highlight
    {
        (string) $highlight = "";
        if ( version_compare(PHP_VERSION, "4.2.0", "<") === 1 )
        {
            ob_start(); // start output buffering to capture contents of highlight
            highlight_string($code);
            $highlight = ob_get_contents(); // capture output
            ob_end_clean(); // clear buffer cleanly
        }
        else
        {
            $highlight=highlight_string($code, true);
        }# Using preg_replace will allow PHP 4 in on the fun
        if ( $inline === true )
            $highlight=preg_replace("/<code>/i","<code class="inline">",$highlight);
        else
            $highlight=preg_replace("/<code>/i","<code class="block">",$highlight);           

                if (

$return === true )
        {
            return $highlight;
        }
        else
        {
            echo $highlight;
        }
    }
?>

You might want to use md5($html_string) instead of "piggusmaloy" as a generally good programming practice. Just in case "piggusmaloy" is actually in $html_string.

Since it had trouble keeping the code intact. (It removed /* )

function showCode($code) {
$code = highlight_string($code, true);
$code = explode("<br />", $code);

$i = "1";
foreach ($code as $line => $syntax) {
  echo "<font color='black'>".$i."</font> ".$syntax."<br>";
  $i++;
}
}

This code takes a php file and highlights it and places a line number next to it.  Great for on the fly debugging.

<?php
// Get a file into an array
$lines = file('index.php');// Loop through our array, show HTML source as HTML source; and line numbers too.
echo('<table border=0 cellpadding=0 cellspacing=0>');
foreach ($lines as $line_num => $line) {
    echo('<tr>');
    echo('<td bgcolor = "#cccccc">');
    echo('<code>' . ($line_num + 1) . '</code>');
    echo('</td>');
    echo('<td>');         
    highlight_string($line);
    echo('</td>');
    echo('</tr>');
